Rajgir in the context of "Patna"

Nalanda (IAST: Nālandā, pronounced [naːlən̪d̪aː]) was a renowned Buddhist mahavihara (great monastery) in medieval Magadha (modern-day Bihar), eastern India. Widely considered to be among the greatest centres of learning in the ancient world and often referred to as "the world's first residential university", it was located near the city of Rajagriha (now Rajgir), roughly 90 kilometres (56 mi) southeast of Pataliputra (now Patna). Operating for almost a thousand years from 427 CE until around 1400 CE, Nalanda mahavihara played a vital role in promoting the patronage of arts, culture and academics during the 5th and 6th century CE, a period that has since been described as the "Golden Age of India" by scholars. The characterisation of Nalanda as a "university" in the modern sense has been challenged by scholars. They argue that while it was undoubtedly a major centre of learning, comparing it directly to a modern university is historically imprecise.

Nalanda was established by emperor Kumaragupta I of the Gupta Empire around 427 CE, and was supported by numerous Indian and Javanese patrons – both Buddhists and non-Buddhists. Nalanda continued to thrive with the support of the rulers of the Pushyabhuti dynasty (r. 500–647 CE) and the Pala Empire (r. 750–1161 CE). After the fall of the Palas, the monks of Nalanda were patronised by the Pithipatis of Magadha. Nalanda was attacked by Huns under Mihirakula in the 5th century and again sustained severe damage from an invasion by the Gauda king of Bengal in the 8th Century. During the final invasion it was burnt down by Muhammad Bakhtiyar Khilji (c. 1200), but it managed to remain operational for decades (or possibly even centuries) following his raids.

Shaishunaga (IAST: Śiśunāga, or Shusunaga) (c. 413 – 395 BCE) was the founder of the Shaishunaga dynasty of the Magadha Empire in the present-day northern India. Initially, he was an amatya (official) of the Magadha empire under the Haryanka dynasty. He was placed on the throne by the people who revolted against the Haryanka dynasty rule. According to the Puranas, he placed his son at Varanasi and himself ruled from Girivraja (Rajagriha). He was succeeded by his son Kalashoka (Kakavarna).

Pataliputra (IAST: Pāṭaliputra), adjacent to modern-day Patna, Bihar, was a city in ancient India, originally built by Magadha ruler Ajatashatru in 490 BCE, as a small fort (Pāṭaligrāma) near the Ganges river. Udayin laid the foundation of the city of Pataliputra at the confluence of two rivers, the Son and the Ganges. He shifted his capital from Rajgriha to Pataliputra due to the latter's central location in the empire.

It became the capital of major powers in ancient India, such as the Shishunaga Empire (c. 413–345 BCE), Nanda Empire (c. 460 or 420 – c. 325 BCE), the Maurya Empire (c. 320–180 BCE), the Gupta Empire (c. 320–550 CE), and the Pala Empire (c. 750–1200 CE). During the Maurya period (see below), it became one of the largest cities in the world. As per the Greek diplomat, traveler and historian Megasthenes, during the Mauryan Empire (c. 320–180 BCE) it was among the first cities in the world to have a highly efficient form of local self government.The location of the site was first identified in modern times in 1892 by Laurence Waddell, published as Discovery of the Exact Site of Asoka's Classic Capital. Extensive archaeological excavations have been made in the vicinity of modern Patna. Excavations early in the 20th century around Patna revealed clear evidence of large fortification walls, including reinforcing wooden trusses.

The Pāḷi Canon is the standard collection of scriptures in the Theravada Buddhist tradition, as preserved in the Pāli language. It is the most complete extant early Buddhist canon. It derives mainly from the Tambapaṇṇiya school.

According to Buddhist tradition, during the First Buddhist Council, three months after the parinibbana of Gautama Buddha in Rajgir, Ananda recited the Sutta Pitaka, and Upali recited the Vinaya Pitaka. The Arhats present accepted the recitations, and henceforth, the teachings were preserved orally by the Sangha. The Tipitaka that was transmitted to Sri Lanka during the reign of King Asoka was initially preserved orally and later written down on palm leaves during the Fourth Buddhist Council in 29 BC, approximately 454 years after the death of Gautama Buddha. The claim that the texts were "spoken by the Buddha" is meant in this non-literal sense.

Tamralipta or Tamralipti (Pali: Tāmaliti) was an ancient port city, located on the coast of the Bay of Bengal. It was the capital of ancient Suhma and Vanga kingdom in Bengal. The Tamluk town in present-day Purba Medinipur, West Bengal, is generally identified as the site of Tamralipti.

It was located near the Rupnarayan river. It gets its name from the Sanskrit term "Tāmra", or copper, which was mined nearby at Ghatsila in the Singbhum region of the Chota Nagpur Plateau and traded through this port. During the Gupta dynasty, Tamralipta was the main emporium, serving as a point of departure for trade with Ceylon, Java, and China, as well as the west. It was linked by roads with the major cities of ancient India of that time, i.e., Rajagriha, Shravasti, Pataliputra, Varanasi, Champa, Kaushambi, and Taxila.

Pawapuri, or Pavapuri (also called Apapapuri, meaning "the sinless town"), is a holy site for Jains located in the Nalanda district of Bihar state in eastern India. It is located about 19 kilometres from Rajgir and 101 kilometres from Patna, the capital of Bihar. Pawapuri is Mahavira's nirvana and a pilgrimage site for Jains.
